CUTTER-BAR.

SPECIFICATION forming part of'Letters Patent No. 265,906, dated October10, 1882.

Application tiled May 9, 1%2. (No model.)

To all whom it may concern:

Be it known'that we, HENRY A.WILLIAMS and WILLIAM A. PRESTON, ofPrinceton, in the county ot' Gibson, and in the State of Indi- 5 ana,have invented certain new and useful Improvements in Gutter-Bars; and wedo hereby ticolare that the following is a full, clear, and exactdescription thereof', reference being had to the accompanying drawings,and to the letio ters of reference marked thereon, making a part ofthisspecification.

rlhis invention has for its objects to provide certain means whereby theknives or cutters may be secured to the cutter-bar of a harvester in aconvenient and reliable manner. These objects we attain by the meansillustrated in the accompanying drawings, in which- Figure l representsa top view ot' a cutterbar showing our invention; Fig. 2, a longizotudinalsection ot' the same; and Fig. 3, aseotional view of the eyeportion ot' the cutter and a portion ot' the bar, showing both in onepiece.

The letter A indicates the cutter-bar, which is provided with recesses Bat suitable distances apurt, having undercut sides for the reception ofthev shanks ot' the cutters or knives G, which are beveled at theiredges so as to tit under the undercut sides of the recesses. The

3o bar is provided with alongitudinal groove, D,A

which contains a bar, E, which is also provided with recesses E', havingundercut sides corresponding to the recesses in the cutter-bar. Thecutter-bar, near one end, is provided with a nut or screw-threadedbearing, F, through which passes a set-screw, G, which is adapted tobear upon the end ot' the longitudinal bar E. The opposite end, E2, ofthe bur is screwthreaded and provided with a nut,lI, as shown.

The letter I indicates the head ot' the cutter- 4o bar, which isprovided with an eye-,rand which may be made separately or in one piecewith said bar, as may prove convenient. The said head is recessed at L,so as to titover the screw nut, and it projects beyond the end ot' thebar, 45 so as to protect the setscrew from dirt and injury. The knivesor cutters are held to their seats by forcing the longitudinal barforward and holding it by means of the set-screw and nut, theundercutrecessesin the said bar hind- 5o ing the cutters to their seats.The cutter-bar is provided with a plate, M,which sets over the end E2 ofthe longitudinal bar and holds it in place.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

ln a cutter-bar, the combination, with the longitudinallygroovedandtransversely recessed main bar, provided with a head made 6o integraltherewith, and having an overhanging portion, of the adjusting screw orbolt and its bearing, whereby the binding-bar is protected, as setforth, and made to bind and hold the knives, substantially as described.

In testimony whereof we at'liX our signatures, in presence otl twowitnesses, this 24th day of March, 1882.
